SUNLU PETG Glow in the Dark 3D Printer Filament - Glow Red, 1.75mm, 1kg

SUNLU PETG Glow in the Dark in Glow Red combines the everyday strength of PETG with a luminous effect: prints absorb light during the day and glow for about 10 minutes once the lights go out. The filament contains 10% luminous powder, giving a glow effect close to glow PLA while keeping PETG's toughness and weather resistance. This 1kg spool of 1.75mm filament suits hobbyists, schools, event decorators and print farms across India.

Charging is easy three ways: 2-3 minutes under UV light, 3-5 minutes in sunlight, or 10-20 minutes under fluorescent light to reach saturation. The filament is held to a tight 1.75 ± 0.02 mm diameter tolerance with laser-monitored production, and SUNLU's neat automated winding prevents knots and tangles. It runs on 99% of FDM printers on the market - Bambu Lab, Creality, Anycubic, Prusa, Elegoo and more.

Key Features

  • Excellent glow-in-the-dark effect: contains 10% luminous powder - charge it with light and prints glow for about 10 minutes in the dark.
  • Three ways to charge: UV light 2-3 minutes, sunlight 3-5 minutes, or fluorescent light 10-20 minutes to saturation.
  • Real PETG strength: the toughness, layer adhesion and weather resistance of SUNLU PETG, plus the glow effect.
  • Less stringing, no clogging: engineered for smooth, consistent extrusion without nozzle blocks.
  • Precise 1.75 ± 0.02 mm diameter: stable feeding and compatibility with 99% of FDM printers.
  • Perfect for decorations: nameplates, signs, logos, jewellery, party and festival decor that comes alive at night.

In the box

  • 1 x SUNLU PETG Glow in the Dark filament spool, Glow Red, 1.75mm, 1kg net weight

Good to know

  • Glow powder is abrasive - a hardened steel nozzle is recommended for long-term use.
  • PETG absorbs moisture; dry at 60-65°C for 4-6 hours if you hear popping or see stringing.
  • Brighter and longer charging light gives a stronger glow; UV charges fastest.
